since they both come from well off families how would you feel if they knew each other when they were younger if only because of their families knowing each other solely based on the fact they're Wealthy And Influential

but their friendship could've been kind of genuine rather than just for social reasons like the rest of their family because they're both dont care and down with the system but also kind of lonely

but then one day it's like "oh you're looking for nobu well sorry but she's gone and we don't really know what happened it's so sad we miss her so much"

(it's very obvious they don't care)

and then after she moves to recolle one day she runs into her again and they can be friends again

although now nobu's a lot grumpier and antisocial and also cut ties with all her money so she's livin the poor life

but they can Make It Work
